[1] According to method 1 of ISO 62 and done on discs ø 50 mm x 3 mm.
[2] The fi gures given for these properties are for the most part derived from raw material supplier data and other publications.
[3] Values for this property are only given here for amorphous materials and for materials that do not show a melting temperature [PBI & PI].
[4] Only for short time exposure [a few hours] in applications where no or only a very low load is applied to the material.
[5] Temperature resistance over a period of min. 20.000 hours. After this period of time, there is a decrease in tensile strength – measured at 23 °C – of about 50 % as compared with the original value. The temperature values
given here are thus based on the thermal-oxidative degradation which takes place and causes a reduction in properties. Note, however, that the maximum allowable service temperature depends in many cases essentially on
the duration and the magnitude of the mechanical stresses to which the material is subjected.
